Claims

[Scope of utility model registration request]

A pilot valve 2 that can automatically switch the operating pressure supply and discharge to the overspeed trip cylinder 1 that can freely stop the engine;
A line A connecting a lubricating oil pipe 3 to this pilot valve 2, a pilot pressure oil line B branching from this line A to the pilot valve 2 via a throttle 4, and a pilot pressure oil line B in parallel with the front throttle 4, and a pilot pressure Line C equipped with a check valve 5 that allows oil to flow only in the direction of line A from oil path B
, a line E connecting the pilot pressure oil passage B to a line D communicating the overspeed trip cylinder 1 with the pilot valve 2, a normally open reset valve 6 provided in this line E, and the line A. A throttle 7 provided near the lubricating oil pipe 3, a check valve 8 provided in line A downstream of this throttle 7, and a check valve 8 connected to line A downstream of this check valve 8, which opens when overspeed occurs. Apart from the normally closed overspeed trip device 9 and the line A,
A safety device for an internal combustion engine comprising a lubricating oil pressure drop trip cylinder 10 and a line F connecting a lubricating oil pipe 3.
